Is it possible to fill in a field on page 3 of a multi-page form with the value that was filled in on page 1? More generally, is it possible to populate a field from another form field. I have seen code that reads fields and outputs to a Post, but that doesn’t help.

There is no built in functionality in Gravity Forms to do that, but there are several solutions.

1. [https://forgravity.com/plugins/live-population/](https://forgravity.com/plugins/live-population/)

2. [https://gravitywiz.com/documentation/gravity-forms-copy-cat/](https://gravitywiz.com/documentation/gravity-forms-copy-cat/)

Without one of those solutions, you could create JavaScript to copy from one input to another in your form.

Thanks for the answer. I would like to try the script solution. I have seen sample PHP. The stripped-down version of code I saw is:

add\_action( ‘gform\_pre\_submission\_6’, ‘pre\_submission\_handler\_region’);  
function pre\_submission\_handler\_region( $form ) {  
country = rgpost( 'input\_30', true ); \_POST[‘input\_35’] = $region; }

- Can I use PHP instead of JavaScript? Should I?
- How do I replace the last step to write to a field instead of writing to Post?
